Hmmm, soloed as SCH, you say? I'm interested, what strategy did you use?
I used the strategy that's near the bottom on Wiki's discussion page. Pulled it to the campaign room, then kited it through the two tunnels that lead from the room to the C.A.
Need movement speed, Desert Boots work fine, as long as you keep Sandstorm up at all times. Assuming it doesn't hit you, it will de-aggro about 20-25 seconds after you cast on it. Everytime it de-aggros, Keep up Sandstorm, Sublimation, Stoneskin, etc... Then pull it again with a Helix, Dia II (Bio supposedly wears off very fast
), or a nuke. Try to cast from max range, or it may hit you if it attempts a TP move (if it uses Microspores to put a Helix on you, it will HURT
It's pretty easy actually, as long as you pay attention. Any mage that can keep MP up, and has some way to enhance movement speed can do it.
